Procedure

Prepared according to the method described in Example 33a) from toluene (5 ml), aqueous sodium carbonate (2 M, 1 ml), (2R)-1-(4-bromophenoxy)-4-(3-pyridyl)-2-butanol (0.25 g, Example 40a), ethanol (1 ml), 3-fluoro-4-propoxybenzeneboronic acid (0.23 g) and tetrakis(triphenylphosphine)palladium(0) (22 mg) with heating at reflux for 4 hours. The residue obtained after work-up was purified by column chromatography over silica eluting with ethyl acetate to give the title compound as a white solid (0.19 g)
